My Orlando Experience v0.3.0

Grounded retrieval release with structured document/source/chunk citations, explicit grounded/abstained status, licensed synthetic fixtures, and a lazy xAI/Grok provider. A real Grok canary ran against synthetic context and passed without storing response content (response SHA-256 bae25f1a1fa83ad042ae00d1b15cb38eda77dca1cd1afd5268d3026b23800714; 158 characters; one citation). No downloaded travel PDFs, derived indexes, or credentials are included.
